DescriptionThis species displays a striking instance of sexual dimorphism. In the male, the forewing is deep bluish black, with cellular, discal, postdiscal and submarginal series of white spots and there is a long narrow bluish white streak in the basal half of space 1b. The hindwing is white with the veins heavily blackened. There are two female forms, both of which resemble the Magpie Crow (Euploea radamanthus radamanthus).

Updates

The latest update in 2008 is consistent with the recent
re-classification developments and updates to C&P4 in the
Malaysian Nature Journal 59(1), pp 1 - 49, and DNA mapping
of the family Nymphalidae by Wahlberg et al, whereby the
Subfamilies Nymphalinae, Heliconiinae, Limenitidinae,
Cyrestinae and Apaturinae are now applicable to the Singapore
checklist. The family Riodinidae, which was earlier placed as
a subfamily of Lycaenidae, has also been reinstated to the
family level.
